If you would like to ogle the SME line of turntables, Sumiko Audio is the US
Distributor. They've got lots of details and pricing info.

The SME 10 becomes the layout model for our project. Compact, open skeleton
plinth. Three-point suspension isolates platter and arm from the motor, which is
carried on board. There is an outboard power supply and motor controller
that comes with. The current price tag on the Model 10, at this time, is
$7999.00 with arm, $6999.00 without arm. Cough, cough,
choke..!

OK, now we take a $200 used Thorens TD160 we just bought off ebay, add some
material and sweat equity and come up with a 'mini model 10'. Will it
compete in the same ball park with the real one...? Of course not but what
we make here should sound quite nice for the money and time spent. Details
below.

R3. Skeleton Plinth Concept based upon Thorens TD150/16x components.

Another concept drawing. This one can work with either TD150 or TD160
essentials. Plinth construction is constrained layers of aluminum and pvc
adhered with polyurethane glue. Same as with R2. The suspension
parts are essentially the same as with R2 but the mounting arrangement is quite
different and more solid. Footers are three BDR cones. Subchassis is
drawn for SME 3009 series II Improved tonearms.

adjustable via slots in the mounting plate. I have retained the safety post that
was used with late TD160 Mk 1 and those that came after.

used in a previous iteration of my TD150 and found to be effective as an
isolator.
